This paper investigates the robust adaptive fault-tolerant control problem for state-constrained continuoustime linear systems with parameter uncertainties, external disturbances, and actuator faults including stuck, outage, and loss of effectiveness. It is assumed that the knowledge of the system matrices, as well as the upper bounds of the disturbances and faults, is unknown. By incorporating a barrier-function like term into the Lyapunov function design, a novel model-free fault-tolerant control scheme is proposed in a parameterdependent form, and the state constraint requirements are guaranteed. The time-varying parameters are adjusted online based on an adaptive method to prevent the states from violating the constraints and compensate automatically the uncertainties, disturbances, and actuator faults. The time-invariant parameters solved by using data-based policy iteration algorithm are introduced for helping to stabilize the system. Furthermore, it is shown that the states converge asymptotically to zero without transgression of the constraints and all signals in the resulting closed-loop system are uniformly bounded. Finally, two simulation examples are provided to show the effectiveness of the proposed approach.

“…In this paper, this problem will be investigated via adaptive dynamic programming (ADP) algorithm. During recent years, some researchers have tried to solve FTC problem for discrete nonlinear systems via ADP algorithm [27,28], where the authors proposed the FTC schemes by combining globalized dual heuristic programming with dynamic model bank. To our knowledge, there is no result on addressing FTC problem via ADP algorithm for unknown continuous nonlinear systems.…”

In this paper, the guaranteed cost faulttolerant control problem for unknown multi-input continuous nonlinear systems with loss of actuator effectiveness faults is investigated using the adaptive dynamic programming algorithm. Initially, by modifying the cost function to account for actuator faults, the problem is transformed into an optimal control problem of the nominal system. Subsequently, by using an existing policy iteration (PI) algorithm to solve the corresponding optimal control problem, a guaranteed cost controller is constructed approximately. Furthermore, a rigorous proof is given to show the convergence of the aforementioned PI algorithm while taking the neural network approximation errors into consideration. Finally, simulation examples are provided to show the effectiveness of the proposed approach.

“…The goal of the proposed approach is to address the two previously stated deficiencies using a building block of an encompassing FTC architecture that combines the adaptation 0019 power of Adaptive Critic Design (ACD) neural control and the reasoning capability of an FTC supervisor [9]. Similar to other such solutions, when initially proposed, the developed architecture also suffered from both deficiencies.…”
